Background: To our knowledge, there has been no prospective study on the results of arthroscopic repair of superior labrum-biceps anchor complex (SLAP) tears with use of modern techniques. The purpose of the present study was to prospectively evaluate the minimum two-year results for patients with type-II SLAP tears that were treated with arthroscopic suture anchor fixation.Methods: Forty-seven patients with symptomatic type-II SLAP tears were evaluated preoperatively and at least two years postoperatively with use of the American Shoulder and Elbow Surgeons (ASES) and L'Insalata outcomes instruments and physical examination. The study group included thirty-nine male and eight female patients with a mean age of thirty-six years; thirty-four of the forty-seven patients were athletes. Patients with rotator cuff tears requiring repair or concomitant shoulder instability were excluded.Results: At an average of 2.7 years, the median ASES and L'Insalata scores were 97 and 93, respectively, compared with baseline scores of 62 and 65 (p < 0.05). The median patient-reported satisfaction rating was 9 (of 10); forty-one patients (87%) rated the outcome as good or excellent. The median patient-reported satisfaction rating was significantly higher for patients with a discrete traumatic etiology than for those with an atraumatic etiology (9 compared with 7); however, there was no significant difference between these groups in terms of the ASES or L'Insalata outcome scores. Overall, twenty-five (74%) of the thirty-four athletes were able to return to their preinjury level of competition, whereas eleven (92%) of the twelve athletes who reported a discrete traumatic event were able to return to their previous level of competition. There were five complications, including four cases of refractory postoperative stiffness.Conclusions: Our findings indicate that favorable outcomes can be anticipated in the majority of patients after arthroscopic SLAP lesion repair. While only three of four patients overall may be capable of returning fully to their previous level of competition, patients with a distinct traumatic etiology have a greater likelihood of a successful return to sports.

Surgical treatment of high-grade acromioclavicular (AC) joint separations has become analogous to ligament reconstructions elsewhere in the body with the goal being restoration of the native anatomy. Circumferential access to the base of the coracoid is essential to reconstruct the coracoclavicular ligament complex. Using some of the traditional open approaches, this access requires detaching the deltoid insertion and performing extensive soft tissue dissection. Also, poor visualization risks injury to nearby neurovascular structures. An arthroscopically assisted reconstruction offers the advantage of less soft tissue dissection and superior visualization to the base of the coracoid. We have developed a unique arthroscopically assisted technique that uses a subacromial approach to pass suture material and a tendon graft around the coracoid to reconstruct the coracoclavicular ligament complex. We describe our technique and preliminary results in 10 patients who have undergone coracoclavicular ligament reconstruction for high-grade AC separation. All patients improved subjectively with regard to pain and function at a minimum followup of 3 months (mean, 5 months; range, 3-18 months). This arthroscopically assisted technique has the potential to allow for safe and at least in the short term reliable restoration of the coracoclavicular ligament complex and provides an alternative technique to treat AC joint separations.

Objective: To provide an overview of the evaluation and treatment of the patient with multidirectional shoulder instability. Data Sources: I searched MEDLINE for the years from 1980 to 2000 using the key words 'shoulder joint,' 'instability,' 'dislocation,' 'multidirectional shoulder instability,' and 'inferior capsular shift.' Data Synthesis: Multidirectional instability is symptomatic glenohumeral subluxation or dislocation in more than 1 direction: anterior, inferior, or posterior. The primary pathology is a loose and patulous capsule, and the entity is more common than previously recognized. Multidirectional instability affects young, sedentary patients with generalized ligamentous laxity, often with bilateral symptoms and an atraumatic history, but it also affects athletes, many of whom have sustained injuries. Patients with multidirectional instability may also have Bankart lesions and humeral head impression defects. Conclusions/Recommendations: Patients with multidirectional instability must be identified before appropriate treatment can be initiated. If a course of rehabilitation fails to improve the patient's symptoms, an inferior capsular shift procedure has been demonstrated to be an effective surgical option. [ABSTRACT FROM AUTHOR]

We used dynamic electromyography and a motion analysis system to describe the muscle firing patterns in 10 shoulder muscles and the basic kinematics of a two-handed overhead medicine ball throw. Ten healthy male subjects with no history of shoulder injury were evaluated. The two-handed medicine ball throw was divided into three phases for analysis: cocking, acceleration, and deceleration. The average duration of the throw was 1.92 seconds; the cocking phase represented 56%, the acceleration phase 15.5%, and the deceleration phase 28.5% of the throw. In the cocking phase, the upper trapezius, pectoralis major, and anterior deltoid muscles showed high activity (>40% to 60% maximum manual test), and the rotator cuff muscles had moderate activity (>20% to 40%). In the acceleration phase, five of the muscles demonstrated high levels of activity (>40% to 60%) and the upper trapezius and lower subscapularis muscles had very high levels of activity (>60%). Analysis of the deceleration phase revealed high activity in the upper trapezius muscle and moderate activity in all other muscles except the pectoralis major. Our findings support the use of medicine ball training as a bridge between static resistive training and dynamic throwing in the rehabilitation of the overhead athlete. This training technique provides a protective method of strengthening that closely simulates portions of the throwing motion. [ABSTRACT FROM AUTHOR]

We reviewed 52 consecutive patients who had undergone arthroscopic labral debridement. The average age was 29 and there were 35 men and 17 women. At operation, 27 patients had superior labrum anterior and posterior (SLAP) lesions, 20 patients had anteroinferior labral lesions, and 5 patients had posterior labral lesions. Despite the fact that, preoperatively, none of these patients had a history of dislocations or clinically evident instability, 70% of the patients with superior labral lesions, and all of those with anteroinferior and posterior lesions had instability on examination under anesthesia. The average followup was 36 months. At 1 year after arthroscopy, 78% of the patients with superior lesions had excellent relief compared with 30% of the patients in the anteroinferior group. At 2 years followup, these results decreased to 63% and 25%, respectively, and only 45% of the patients with superior labral lesions and 25% of those with anteroinferior lesions had returned to their previous athletic performance level. Four patients required a reoperation: 2 for instability and 2 for impingement. We conclude that occult instability is frequently present in patients with glenoid labral tears. The overall results are not encouraging, but this procedure may have an indication for short-term goals in competitive athletes or those who are willing to accept some compromise in function.

Background: The rate of anterior cruciate ligament (ACL) rupture in active, skeletally immature patients is increasing. Although hamstring tendon autograft (HTA) was previously deemed the gold standard, recent studies have shown HTA to have a high failure rate in this high-risk population of young competitive athletes, and quadriceps tendon autograft (QTA) has yielded excellent preliminary outcomes in some studies examining this population., Purpose: To evaluate 3-year clinical and patient-reported functional outcomes of primary ACL reconstruction (ACLR) with soft tissue QTA in skeletally immature patients., Study Design: Case series; Level of evidence, 4., Methods: Skeletally immature patients who underwent ACLR with a full-thickness soft tissue QTA were included. Preoperative patient and surgical data were collected. The ACLR technique was selected predicated upon skeletal age and included all-epiphyseal and complete transphyseal techniques. Patients were followed for a minimum of 2 years with successive clinical visits or were contacted via telephone. Patients who did not have minimum 2-year follow-up after 3 contact attempts via telephone were excluded. Information regarding return to sports (RTS) and concomitant or subsequent surgical procedures was collected. Pediatric International Knee Documentation Committee (Pedi-IKDC), Hospital for Special Surgery Functional Activity Brief Scale (HSS Pedi-FABS), and Single Assessment Numeric Evaluation (SANE) scores were collected., Results: Of 85 adolescent patients aged 11.1 to 17.6 years (mean age, 14.1 ± 1.2 years), 2 patients were determined to be lost to follow-up after 3 failed contact attempts. Of the patients included in this study (N = 83), 26 patients (31%) underwent all-epiphyseal and 57 patients (69%) underwent complete transphyseal ACLR. Additionally, 48 patients (58%) underwent concomitant lateral extra-articular tenodesis using the iliotibial band with a modified Lemaire technique. The mean follow-up time was 3.7 ± 1.2 years (range, 2-7 years). Twenty (24%) patients had subsequent surgical procedures, of which 3 (4%) were due to graft failures. At a mean 3-year follow-up, the mean Pedi-IKDC, HSS Pedi-FABS, and SANE scores were 90, 23, and 94 respectively; the RTS rate was 100%; and the rate of RTS at the previous level of performance was 93%., Conclusion: Use of a soft tissue QTA for ALCR in a high-risk skeletally immature population of athletes resulted in excellent postoperative outcomes with low rates of graft failure and high return to sport rates., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: F.A.C. has received royalties from Arthrex, Saunders Mosby Elsevier, and Wolters-Kluwer Health Lippincott Williams and Wilkins; consulting fees from Arthrex; and support for education from Gotham Surgical Solutions & Devices.

Background: There are various reported complications after primary anterior cruciate ligament reconstruction (ACLR) necessitating additional surgery in skeletally immature patients, regardless of technique and autograft type., Purpose: To analyze the rate and type of complications encountered with soft tissue quadriceps tendon autograft (QTA) for ACLR in patients ≤18 years as well as the overall rate of second surgery, unrelated to the use of the QTA., Study Design: Case series; Level of evidence, 4., Methods: A total of 141 patients ≤18 years who underwent ACLR with a QTA and had minimum 6-month follow-up were included. All patients underwent ACLR by utilizing a full-thickness soft tissue QTA. Complications associated with the QTA harvest site and use of QTA were reported., Results: The mean age of the included cohort (84 men, 57 women) was 14.8 ± 1.6 years. The average follow-up was of 2.0 ± 1.2 years. A total of 30 (21%) patients had a subsequent complication that required surgical intervention; in 11 (8%) patients, the complication was specifically associated with the use of a QTA, whereas in 19 (13%) patients, the complication was related to the ACLR. In addition, 13 (9%) patients underwent a contralateral ACLR procedure. Of the QTA-related complications, 2 patients developed osteochondritis dissecans (OCD)-like lesions in the superior aspect of the patella, 2 patients had injured their quadriceps extensor mechanism and required surgical repair, and 8 patients had a subsequent procedure to remove nonabsorbable sutures used for donor site quadriceps tendon closure. One of the patients who underwent the removal of nonabsorbable sutures also had an arthroscopic debridement of patellar chondral damage., Conclusion: We reported complications encountered with soft tissue QTA for ACLR. The complication rate for QTA harvest was 8%. However, given that the removal of nonabsorbable sutures from the donor site was caused by the surgical technique used, the revised nonsuture-related complication rate for QTA graft harvest was 2%. Although the use of a QTA has recently gained popularity due to its high return-to-sport and low graft-failure rates, surgeons should be aware of the complications associated with using this graft type., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: F.A.C. has received consulting fees from Arthrex; nonconsulting fees from Arthrex; royalties from Arthrex, Elsevier, and Wolters Kluwer Health; and financial or material support from Elsevier and Wolters Kluwer Health.

Background: Quadriceps tendon autograft (QTA) has recently gained popularity in the treatment of anterior cruciate ligament (ACL) ruptures in pediatric patients. The addition of lateral extra-articular tenodesis (LET) to an ACL reconstruction (ACLR) has been found to reduce the risk of ACL retear in high-risk patients., Purpose: To (1) compare ACL graft maturity using signal intensity ratios (SIRs) on magnetic resonance imaging (MRI) scans in skeletally immature patients undergoing ACLR with QTA either with or without concomitant LET and (2) evaluate LET safety by calculating the physeal disturbance-related reoperation rate in the ACLR+LET group., Study Design: Cohort study; Level of evidence, 3., Methods: The records of patients aged ≤18 years who underwent ACLR between 2015 and 2021 were reviewed retrospectively. Patients undergoing ACLR with QTA who had open distal femoral and proximal tibial physes on MRI scans and a minimum 2-year follow-up data were included. SIR values were measured on sagittal MRI scans by averaging the signal at 3 regions of interest along the ACL graft and dividing by the signal of the posterior cruciate ligament at its insertion. Statistical analysis was performed to evaluate differences in SIR values at 6 months, 1 year, and 2 years postoperatively in patients who underwent ACLR alone versus ACLR+LET., Results: Overall, 29 patients were included in the study: 16 patients in the ACLR+LET group and 13 patients in the ACLR-only group. There were no significant differences in SIR values between groups at the 6-month or 1-year postoperative timepoints. At 2 years postoperatively, the median SIR of the ACLR+LET group was significantly lower than that of the ACLR-only group on both univariate (1.33 vs 1.86, respectively, P  = .0012) and multivariate regression analyses adjusting for both sex and surgical technique (β = -0.49 [95% CI, -0.91 to -0.05]; P  = .029). There were no cases of reoperation for physeal disturbance in patients who underwent ACLR+LET., Conclusion: The addition of LET to an ACLR with QTA was associated with lower average SIR values and thus improved graft maturity at 2 years postoperatively compared with ACLR alone in skeletally immature patients. The addition of LET to an ACLR was found to be safe in skeletally immature patients., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: F.A.C. has received nonconsulting services from Arthrex, royalties from Arthrex, and consulting fees from Arthrex.

Background: Radiographic measurements of limb alignment in skeletally immature patients with anterior cruciate ligament (ACL) tears are frequently used for surgical decision-making, preoperative planning, and postoperative monitoring of skeletal growth. However, the interrater and intrarater reliability of these radiographic characteristics in this patient population is not well documented., Hypothesis: Excellent reliability across 4 raters will be demonstrated for all digital measures of length, coronal plane joint orientation angles, mechanical axis, and tibial slope in skeletally immature patients with ACL tears., Study Design: Cohort study (diagnosis)., Methods: Three fellowship-trained orthopaedic surgeons and 1 medical student performed 2 rounds of radiographic measurements on digital imaging (lateral knee radiographs and long-leg radiographs) of skeletally immature patients with ACL tears. Intrarater and interrater reliability for continuous radiographic measurements was assessed with intraclass correlation coefficients (ICCs) across 4 raters with 95% CIs for affected and unaffected side measurements. Interrater reliability analysis used an ICC (2, 4) structure and intrarater reliability analysis used an ICC (2, 1) structure. A weighted kappa coefficient was calculated for ordinal variables along with 95% CIs for both interrater and intrarater reliability. Agreement statistic interpretations are based on scales described by Fleiss, and Cicchetti and Sparrow: <0.40, poor; 0.40 to 0.59, fair; 0.60 to 0.74, good; and >0.74, excellent., Results: Radiographs from a convenience sample of 43 patients were included. Intrarater reliability was excellent for nearly all measurements and raters. Interrater reliability was also excellent for nearly all reads for all measurements., Conclusion: Radiographic reliability of long-leg radiographs and lateral knee x-rays in skeletally immature children with ACL tears is excellent across nearly all measures and raters and can be obtained and interpreted as reliable and reproducible means to measure limb length and alignment., Level of Evidence: Level III., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: The incidence of anterior cruciate ligament (ACL) reconstruction (ACLR) in children and adolescents has increased significantly, and many such patients are at increased risk for ACL retear. Lateral extra-articular tenodesis (LET) may be performed in conjunction with ACLR to reduce the risk of ACL retear., Purpose: To evaluate the 2-year clinical outcomes of ACLR with soft tissue quadriceps tendon (QUAD) autograft performed with a concomitant LET using a modified Lemaire technique in skeletally immature patients., Study Design: Case series; Level of evidence, 4., Methods: A consecutive series of adolescent patients who underwent QUAD autograft ACLR and LET with a minimum of 2 years of follow-up data were analyzed retrospectively. ACLR techniques, including all-epiphyseal and complete transphyseal, were indicated based on skeletal age. Outcome measures included return to sports, concomitant or subsequent surgical procedures, and multiple patient-reported outcome measures, including Single Assessment Numeric Evaluation (SANE), Pediatric International Knee Documentation Committee (Pedi-IKDC), and Hospital for Special Surgery Pediatric Functional Activity Brief Scale (HSS Pedi-FABS) scores., Results: The final cohort included 49 consecutive adolescent patients aged 11 to 16 years (mean, 14.2 ± 1 years) with a minimum follow-up of 2 years. One patient was lost to follow-up. Of the patients included in the study (N = 48; 27 male, 21 female), 98% participated in high-risk competitive sports. Two (4%) patients were undergoing revision ACLR. Thirty-eight (79%) patients underwent complete transphyseal, and 10 (21%) patients underwent all-epiphyseal ACLR. Sixteen (33%) patients had subsequent surgical procedures, including 5 contralateral ACLR, 4 meniscal surgery, 4 QUAD autograft scar revision, 4 irrigation and debridement (2 patients, 2 each), and 3 hardware removal (2 for hemi-epiphysiodesis and 1 tibial socket button removal) procedures. The rate of graft rupture was 0%. At a mean follow-up of 3.4 ± 1.2 years (range, 2-7 range), the mean SANE score was 93, the mean Pedi-IKDC score was 89, and the mean HSS Pedi-FABS score was 23. The return-to-sports rate was 100%., Conclusion: An LET performed concomitantly with an ACLR is safe and should be considered as a concomitant procedure for adolescent patients with nonmodifiable risk factors who are at high risk of retear.

Introduction: Anterior cruciate ligament (ACL) ruptures are common amongst paediatric patients, especially those participating in competitive sports. While magnetic resonance imaging (MRI) is typically used to confirm the diagnosis, certain radiologic findings can be indicative of an ACL tear, including a lateral femoral notch sign (LFNS) > 1.5 mm (mm). No study has focussed on understanding the resolution pattern of the LFNS in paediatric patients following ACL reconstruction (ACLR). The aim of this study is to determine whether the depth of the LFNS regresses following ACLR. The authors hypothesize that following ACLR, the LFNS will resolve., Methods: All patients who were treated for acute ACL rupture by one of two paediatric orthopaedic surgeons between 2015 and 2020 were collected; 321 patients with the age of 5-18 were collected. Patients were excluded if they underwent previous ipsilateral knee surgeries and if they did not have pre-operative knee radiographs; 274 patients met inclusion criteria. LFNS was measured on pre-operative (PreOp) and most recent post-operative (PostOp) radiographs. A comparison cohort of patients with an LFNS <1.5 mm matched by age within 1.5 years, sex, and laterality was also collected. The median difference was calculated by taking the difference between PreOp LFNS and PostOp LFNS of each participant and finding the median of those values., Results: A total of 274 pre-operative radiographs were analysed for an LFNS depth >1.5 mm. Seventeen radiographs met these criteria with a median age of 16.3 years and a median depth of 1.70 mm. Of the 17 radiographs, 8 (47.1%) of participants were skeletally immature. The median LFNS depth at most recent follow-up and median percent decrease were 1.50 mm and 28%, respectively. Only 11.8% of patients demonstrated no change in LFNS depth from PreOp to PostOp imaging. Wilcoxon signed-rank test indicated that the PreOp LFNS was significantly greater than the PostOp LFNS (p < 0.001). Mann-Whitney U tests with cases and the comparison cohort demonstrated no difference in the percent decrease (p = 0.106)., Conclusion: This study sought to understand the resolution of the LFNS depth following initial ACL rupture. At a median of 7.67 months following ACLR, the LFNS depth decreased significantly by 0.60 mm. These findings suggest that following ACL rupture, the paediatric LFNS has the potential to resolve. Future studies should aim to further assess the resolution pattern of the LFNS with advanced imaging, such as MRI., Competing Interests: Declaration of competing of interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Daniel W.

All-epiphyseal anterior cruciate ligament reconstruction (AE ACLR) has become an alternative technique for skeletally immature patients with a significant amount of growth remaining. This technique involves graft fixation within the epiphysis without crossing the physis. Either quadriceps tendon or hamstring autograft can be used when performing this procedure. Previous studies have shown that the complication rate is not higher in AE techniques versus previously developed techniques. Additionally, in our hands, the revision rate was found to be significantly lower in an AE ACLR compared with patients who had a transphyseal ACLR., (Published by Elsevier Inc.)

Background and Hypothesis: Arthroscopic rotator cuff repair surgery is one of the most common shoulder procedures performed in the United States. Although several studies have shown considerable symptomatic relief in the short term following surgery, a relatively high rate of recurrent defects has led surgeons to question the long-term durability of this operation. We hypothesized that outcomes at a minimum of 15 years of follow-up in patients who underwent all-arthroscopic rotator cuff repair would be maintained and would remain significantly improved compared with the preoperative status., Methods: All-arthroscopic rotator cuff repairs were performed in 193 patients from 2003 to 2005. Patient-reported outcomes were collected preoperatively and at 1, 2, 5, and ≥15 years postoperatively. The primary outcome was the American Shoulder and Elbow Surgeons (ASES) score. Secondary outcomes included Single Assessment Numeric Evaluation (SANE), Shoulder Activity Scale (SAS), visual analog scale, and Patient-Reported Outcomes Measurement Information System (PROMIS)-Upper Extremity (UE) scores. Patient demographic characteristics, revision surgical procedures, and complications were recorded. Generalized estimating equations were used to model scores over time, and multiple comparisons between time points were performed using Tukey adjustment., Results: This study included 60 patients with a mean follow-up period of 16.5 years (range, 15.8-17.7 years). The mean ASES score improved from 60.2 ± 18.8 preoperatively to 93.0 ± 9.4 at ≥15 years (P < .0001). The mean visual analog scale pain score decreased from 4.1 ± 0.7 preoperatively to 0.7 ± 0.3 at ≥15 years (P < .0001). The average SANE, SAS, and PROMIS-UE scores at ≥15 years were 87.8 ± 14.8, 8.8 ± 4.3, and 49.6 ± 10.2, respectively. Of 60 patients, 7 underwent revision surgery. Older age and female sex were associated with lower SAS scores at 15 years, whereas female sex was associated with lower PROMIS-UE scores. There were no factors predictive of ASES or SANE scores., Conclusion: At long-term follow-up (≥15 years), the patient-reported outcomes of all-arthroscopic rotator cuff repair show significant improvement from baseline preoperative function and remain durable over a period of 15 years. This information is useful in counseling patients regarding the long-term results of this procedure., (Copyright © 2022. Published by Elsevier Inc.)

Purpose: Disturbance of the growth plate during all-epiphyseal anterior cruciate ligament reconstruction (ACLR) socket placement is possible due to the undulation of the distal femoral physis and proximal tibial physis. Therefore, it is important to obtain intraoperative imaging of the guide wire prior to reaming the socket. The purpose of this study was to investigate the effect of the use of 3D intraoperative fluoroscopy on socket placement in patients undergoing all-epiphyseal ACLR. It was hypothesized that 3D imaging would allow for more accurate intraoperative visualization of the growth plate and hence a lower incidence of growth plate violation compared to 2D imaging., Methods: Patients under the age of 18 who underwent a primary all-epiphyseal ACL reconstruction by the senior authors and had an available postoperative MRI were retrospectively reviewed. Demographic data, surgical details, and the distances between the femoral socket and distal femoral physis (DFP) and tibial socket and proximal tibial physis (PTP) were recorded. Patients were split into two groups based on type of intraoperative fluoroscopy used: a 2D group and a 3D group. Interrater reliability of radiographic measurements was evaluated using intraclass correlation coefficient (ICC)., Results: Seventy-two patients fit the inclusion criteria and were retrospectively reviewed. 54 patients had 2D imaging and 18 patients had 3D imaging. The mean age at time of surgery was 12.3 ± 1.5 years, 79% of patients were male, and 54% tore their left ACL. The mean time from surgery to postoperative MRI was 2.0 ± 1.1 years. The ICC was 0.92 (95% CI 0.35-0.98), indicating almost perfect interrater reliability. The mean difference in distance between the tibial socket and the PTP was significantly less in the 2D imaging group than the 3D imaging group (1.2 ± 1.7 mm vs 2.5 ± 2.2 mm, p = 0.03). The femoral and tibial sockets touched or extended beyond the DFP or PTP, respectively, significantly less in the 3D group than in the 2D group (11% vs 43%, p < 0.000, 17% vs 65%, p < 0.000)., Conclusion: There was a significantly increased distance from the PTP and decreased incidence of DFP violation with use of 3D intraoperative imaging for all-epiphyseal ACLR socket placement. Surgeons should consider utilizing 3D imaging prior to creating femoral and tibial sockets to potentially decrease the risk of physis violation in these patients., Level of Evidence: III., (© 2021.

Background: Growth disturbance is an uncommon but potentially serious complication after anterior cruciate ligament (ACL) reconstruction in skeletally immature patients., Purpose: To describe how the pediatric ACL literature has assessed preoperative skeletal maturity and the amount of growth remaining and to comprehensively review the incidence, reporting, and monitoring of postoperative growth disturbance., Study Design: Systematic review; Level of evidence, 4., Methods: This review included studies reporting original research of clinical outcomes of skeletally immature patients after ACL reconstruction. Patient characteristics, surgical techniques, preoperative assessments of skeletal maturity or growth remaining, and postoperative assessments of growth disturbances were extracted., Results: A total of 100 studies met inclusion criteria. All studies reported chronological age, and 28 studies (28%) assessed skeletal age. A total of 44 studies (44%) used Tanner staging, and 12 studies (12%) obtained standing hip-to-ankle radiographs preoperatively. In total, 42 patients (2.1%) demonstrated a leg length discrepancy (LLD) >10 mm postoperatively, including 9 patients (0.5%) with LLD >20 mm; furthermore, 11 patients (0.6%) with LLD underwent growth modulation. Shortening was the most common deformity overall, but overgrowth was reported more frequently in patients who had undergone all-epiphyseal techniques. Most LLDs involved the femur (83%). A total of 26 patients (1.3%) demonstrated a postoperative angular deformity ≥5°, and 9 of these patients underwent growth modulation. The most common deformities were femoral valgus (41%), tibial recurvatum (33%), and tibial varus (22%). Although standing hip-to-ankle radiographs were the most common radiographic assessment of growth disturbance, most studies inadequately reported the clinical and radiographic methods of assessment for growth disturbance. Additionally, only 35% of studies explicitly followed patients to skeletal maturity., Conclusion: This systematic review described significant variability in the reporting and monitoring of growth-related complications after ACL reconstruction in skeletally immature patients. The incidence of LLD and angular deformity appeared to be low, but the quality of research was not comprehensive enough for accurate assessment., Registration: CRD42019136059 (PROSPERO).

Background: Treatment options for pediatric and adolescent anterior cruciate ligament (ACL) injuries include early operative, delayed operative, and nonoperative management. Currently, there is a lack of consensus regarding the optimal treatment for these injuries., Purpose/hypothesis: The purpose was to determine the optimal treatment strategy for ACL injuries in pediatric and adolescent patients. We hypothesized that (1) early ACL reconstruction results in fewer meniscal tears than delayed reconstruction but yields no difference in knee stability and (2) when compared with nonoperative management, any operative management results in fewer meniscal tears and cartilage injuries, greater knee stability, and higher return-to-sport rates., Study Design: Systematic review and meta-analysis; Level of evidence, 4., Methods: A systematic search of databases was performed including PubMed, Embase, and Cochrane Library using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Inclusion criteria were a pediatric and adolescent patient population (≤19 years old at surgery), the reporting of clinical outcomes after treatment of primary ACL injury, and original scientific research article. Exclusion criteria were revision ACL reconstruction, tibial spine avulsion fracture, case report or small case series (<5 patients), non-English language manuscripts, multiligamentous injuries, and nonclinical studies., Results: A total of 30 studies containing 50 cohorts and representing 1176 patients met our criteria. With respect to nonoperative treatment, knee instability was observed in 20% to 100%, and return to preinjury level of sports ranged from 6% to 50% at final follow-up. Regarding operative treatment, meta-analysis results favored early ACL reconstruction over delayed reconstruction (>12 weeks) for the presence of any meniscal tear (odds ratio, 0.23; P = .006) and irreparable meniscal tear (odds ratio, 0.31; P = .001). Comparison of any side-to-side differences in KT-1000 arthrometer testing did not favor early or delayed ACL reconstruction in either continuous mean differences ( P = .413) or proportion with difference ≥3 mm ( P = .181). Return to preinjury level of competition rates for early and delayed ACL reconstruction ranged from 57% to 100%., Conclusion: Delaying ACL reconstruction in pediatric or adolescent patients for >12 weeks significantly increased the risk of meniscal injuries and irreparable meniscal tears; however, early and delayed operative treatment achieved satisfactory knee stability. Nonoperative management resulted in high rates of residual knee instability, increased risk of meniscal tears, and comparatively low rates of return to sports.

Background: Hamstring tendon autograft (HTA) is a common graft choice for anterior cruciate ligament (ACL) reconstruction (ACLR) in skeletally immature patients. Recently, the use of quadriceps tendon autograft (QTA) has shown superior preliminary outcomes in this population., Purpose: To evaluate graft maturity by comparing magnetic resonance imaging (MRI) signal intensity of HTA versus QTA used in primary ACLR., Study Design: Cohort study; Level of evidence, 3., Methods: All patients under the age of 18 years who underwent a primary ACLR by the senior authors using either an HTA or a QTA were retrospectively reviewed. A total of 70 skeletally immature patients (37 in the HTA group and 33 in the QTA group) with an available MRI at 6 and 12 months postoperatively were included. Signal intensity ratio (SIR) was measured on sagittal MRI by averaging the signal at 3 regions of interest along the ACL graft and dividing by the signal of the tibial footprint of the posterior cruciate ligament. Statistical analysis was performed to determine interrater reliability and differences between time points and groups., Results: Age, sex, and type of surgery were not associated with any differences in SIR. There was no significant difference in SIR between groups on the 6-month MRI. However, the SIR of the QTA group was significantly less than in the HTA group on the 12-month MRI (2.33 vs 2.72, respectively; P = .028). Within the HTA group, there was no significant difference in SIR at either MRI time point. In the QTA group, there was a significant decrease in SIR between the 6-month and 12-month postoperative MRI (2.70 vs 2.33, respectively; P = .045)., Conclusion: These findings suggest improved graft maturation, remodeling, and structural integrity of the QTA compared with the HTA between 6 and 12 months postoperatively. This provides evidence that, at 1 year postoperatively, QTA may have a superior rate of incorporation and synovialization as compared with the HTA.

Background: Management of massive irreparable rotator cuff tears (MIRCTs) remains controversial owing to variability in patient features and outcomes contributing to a lack of unanimity in treatment recommendations. The purpose of this study was to implement the Delphi process using experts from the Neer Circle of the American Shoulder and Elbow Surgeons to determine areas of consensus regarding treatment options for a variety of MIRCTs., Methods: A panel of 120 shoulder surgeons were sent a survey regarding MIRCT treatments including arthroscopic débridement and partial cuff repair, graft augmentation, reverse shoulder arthroplasty (RSA), superior capsular reconstruction (SCR), and tendon transfer. An iterative Delphi process was then conducted with a first-round questionnaire consisting of 13 patient factors with the option for open-ended responses to identify important features influencing the treatment of MIRCTs. The second-round survey sought to determine the importance of patient factors related to the 6 included treatment options. A third-round survey asked participants to classify treatment options for 60 MIRCT patient scenarios as either preferred treatment, acceptable treatment, not acceptable/contraindicated, or unsure/no opinion. Patient scenarios were declared to achieve consensus for the preferred and not acceptable/contraindicated categories when at least 80% of the survey respondents agreed on a response, and a 90% threshold was required for the acceptable treatment category, defined by an acceptable treatment or preferred treatment response., Results: Seventy-two members agreed to participate and were deemed to have the requisite expertise to contribute based on their survey responses regarding clinical practice and patient volume. There were 20 clinical scenarios that reached 90% consensus as an acceptable treatment, with RSA selected for 18 scenarios and arthroscopic débridement and/or partial repair selected for 2. RSA was selected as the singular preferred treatment option in 8 scenarios. Not acceptable/contraindicated treatment options reached consensus in 8 scenarios, of which, 4 related to SCR, 3 related to RSA, and 1 related to partial repair with graft augmentation., Conclusion: This Delphi process exhibited significant consensus regarding RSA as a preferred treatment strategy in older patients with pseudoparesis, an irreparable subscapularis, and dynamic instability. In addition, the process identified certain unacceptable treatments for MIRCTs such as SCR in older patients with pseudoparesis and an irreparable subscapularis or RSA in young patients with an intact or reparable subscapularis without pseudoparesis or dynamic instability. The publication of these scenarios and areas of consensus may serve as a useful guide for practitioners in the management of MIRCTs., (Copyright © 2021 Journal of Shoulder and Elbow Surgery Board of Trustees.

Purpose: To report clinical and functional outcomes including return to preinjury activity level following arthroscopic-assisted coracoclavicular (CC) ligament reconstruction (AA-CCR) and to determine associations between return to preinjury activity level, radiographic outcomes, and patient-reported outcomes following AA-CCR., Methods: A institutional registry review of all AA-CCR using free tendon grafts from 2007 to 2016 was performed. Clinical assessment included Single Assessment Numeric Evaluation (SANE) score and return to preinjury activity level at final follow-up. Treatment failure was defined as (1) revision acromioclavicular stabilization surgery, (2) unable to return to preinjury activity level, or (3) radiographic loss of reduction (RLOR, >25% CC distance compared with contralateral side). SANE scores, return to activity, and RLOR were compared between patients within each category of treatment failure, by grade of injury, and whether concomitant pathology was treated., Results: There were 88 patients (89.8% male) with mean age of 39.6 years and minimum 2-year clinical follow-up (mean 6.1 years). Most injuries were Rockwood grade V (63.6%). Mean postoperative SANE score was 86.3 ± 17.5. Treatment failure occurred in 17.1%: 8.0% were unable to return to activity, 5.7% had RLOR, and 3.4% underwent revision surgery due to traumatic reinjury. SANE score was lower among patients who were unable to return to activity compared with those with RLOR and compared with nonfailures (P = .0002). There were no differences in revision surgery rates, return to activity, or SANE scores according to Rockwood grade or if concomitant pathology was treated., Conclusions: AA-CCR with free tendon grafts resulted in good clinical outcomes and a high rate of return to preinjury activity level. RLOR did not correlate with return to preinjury activity level. Concomitant pathology that required treatment did not adversely affect outcomes. Return to preinjury activity level may be a more clinically relevant outcome measure than radiographic maintenance of acromioclavicular joint reduction., Level of Evidence: IV (Case Series)., (Copyright © 2020.

Background: The treatment of patients who sustain a first-time anterior glenohumeral dislocation (FTAGD) is controversial. The purpose of this study was to find consensus among experts using a validated iterative process in the treatment of patients after an FTAGD., Methods: The Neer Circle is an organization of shoulder experts recognized for their service to the American Shoulder and Elbow Surgeons. Consensus among 72 identified experts from this group was sought with a series of surveys using the Delphi process. The first survey used open-ended questions designed to identify patient-related features that influence treatment decisions after an FTAGD. The second survey used a Likert scale to rank each feature's impact on treatment decisions. The third survey used highly impactful features to construct 162 clinical scenarios. For each scenario, experts recommended surgery or not and reported how strongly they made their recommendation. These data were analyzed to find clinical scenarios that had >90% consensus for recommending treatment. These data were also used in univariate and multivariate mixed-effects models to identify odds ratios (ORs) for different features and to assess how combining these features influenced the probability of surgery for specific populations., Results: Of the 162 scenarios, 8 (5%) achieved >90% consensus for recommending surgery. All of these scenarios treated athletes with meaningful bone loss at the end of their season. In particular, for contact athletes aged > 14 years who were at the end of the season and had apprehension and meaningful bone loss, there was >90% consensus for recommending surgery after an FTAGD, with surgeons feeling very strongly about this recommendation. Of the scenarios, 22 (14%) reached >90% consensus for recommending nonoperative treatment. All of these scenarios lacked meaningful bone loss. In particular, surgeons felt very strongly about recommending nonoperative treatment after an FTAGD for non-athletes lacking apprehension without meaningful bone loss. The presence of meaningful bone loss (OR, 6.85; 95% confidence interval, 6.24-7.52) and apprehension (OR, 5.60; 95% confidence interval, 5.03-6.25) were the strongest predictors of surgery. When these 2 features were combined, profound effects increasing the probability of surgery for different populations (active-duty military, non-athletes, noncontact athletes, and contact athletes) were noted, particularly non-athletes., Conclusion: Consensus for recommending treatment of the FTAGD patient was not easily achieved. Certain combinations of patient-specific factors, such as the presence of meaningful bone loss and apprehension, increased the probability of surgery after an FTAGD in all populations. Over 90% of shoulder instability experts recommend surgery after an FTAGD for contact athletes aged > 14 years at the end of the season with both apprehension and meaningful bone loss. Over 90% of experts would not perform surgery after a first dislocation in patients who are not athletes and who lack apprehension without meaningful bone loss., (Copyright © 2020 Journal of Shoulder and Elbow Surgery Board of Trustees.

Background: Pre- and postoperative standing hip-to-ankle radiographs are critical for monitoring potential postoperative growth arrest and resultant deformities after pediatric anterior cruciate ligament (ACL) reconstruction., Purpose: To determine the prevalence of apparent preoperative leg-length discrepancies (LLDs) that resolve at the first postoperative radiographic examination in patients undergoing ACL reconstruction in order to understand what proportion of the noted preoperative deformities may have been inaccurate., Study Design: Case series; Level of evidence, 4., Methods: A retrospective review of prospectively collected preoperative and first postoperative full-length hip-to-ankle radiographs was performed in a cohort of skeletally immature patients who had an acute ACL injury and underwent subsequent surgical reconstruction. Leg length measurements for both the injured and the uninjured legs were obtained for comparison., Results: A total of 112 patients (mean age, 12.7 ± 1.7 years) were included (79 boys and 33 girls). Leg-length measurement interrater reliability among 3 raters for 25 randomly chosen images was nearly perfect (intraclass correlation coefficient, 0.996; 95% CI, 0.994-0.998). At baseline, there was no apparent preoperative LLD (<5 mm) in 48% (n = 54) of participants, while 37% (n = 41) displayed a small apparent LLD (5 to <10 mm), 12% (n = 13) displayed a moderate apparent LLD (10 to <15 mm), and 4% (n = 4) displayed a large apparent LLD (≥15 mm). Of the patients with an apparent preoperative LLD, 66% (n = 38) of them tore their ACL on the leg measuring shorter. At first postoperative radiographs, 48% (n = 28) of patients with an apparent preoperative LLD showed resolution to no LLD: 46% (n = 19) of patients with a small apparent preoperative LLD, 54% (n = 7) of patients with a moderate apparent LLD, and 50% (n = 2) of patients with a large apparent LLD., Conclusion: A high percentage of patients (48%) with apparent preoperative LLDs showed resolution to no LLDs by their first postoperative imaging, indicating that preoperative hip-to-ankle radiographs display some false LLDs in patients with recent ACL tears who are unable to fully extend their injured leg and bear weight.

Historically, one of the most common graft choices for anterior cruciate ligament (ACL) reconstruction in the pediatric population has been the hamstring autograft. Although pediatric ACL reconstructions with a hamstring autograft have allowed a majority of children and adolescents to return to athletics, it has been reported that anywhere between 6% and 38% of these patients will go on to experience subsequent graft rupture. The quadriceps tendon autograft is an alternative to the hamstring tendon autograft that demonstrates superior preliminary outcomes, and we currently recommend it for skeletally immature patients undergoing primary and revision ACL reconstruction. This paper aims to describe our technique for an open full-thickness quadriceps tendon harvest with repair., (© 2020 by the Arthroscopy Association of North America. Published by Elsevier.)

Background: Scapular fractures following reverse total shoulder arthroplasty (RSA) are devastating complications with substantial functional implications. The role of the coracoacromial ligament (CAL), which is often transected during surgical exposure for RSA, is not fully known. We hypothesized that the CAL contributes to the structural integrity of the "scapular ring" and that the transection of this ligament during RSA alters the scapular strain patterns., Methods: RSA was performed on 8 cadaveric specimens without evidence of a prior surgical procedure in the shoulder. Strain rosettes were fixed onto the acromial body (at the location of Levy type-II fractures) and the scapular spine (Levy type III). With use of a shoulder simulator, strains were recorded at 0°, 30°, and 60° glenohumeral abductions before and after CAL transection. The deltoid and glenohumeral joints were functionally loaded (middle deltoid = 150 N, posterior deltoid = 75 N, and joint compression = 300 N). Maximum principal strains were calculated from each rosette at each abduction angle. A repeated-measures analysis of variance with post hoc analysis was performed to compare the maximum principal strain at each abduction angle., Results: With the CAL intact, there was no significant difference between strain experienced by the acromion and scapular spine at 0°, 30°, and 60° of glenohumeral abduction. CAL transection generated significantly increased strain in the scapular spine at all abduction angles compared with an intact CAL. The maximum scapular spine strain observed was increased 19.7% at 0° of abduction following CAL transection (1,216 ± 300.0 microstrain; p = 0.011). Following CAL transection, acromial strains paradoxically decreased at all abduction angles (p < 0.05 for all). The smallest strains were observed at 60° of glenohumeral abduction at the acromion following CAL transection (296 ± 121.3 microstrain; p = 0.048)., Conclusions: The CAL is an important structure that completes the "scapular ring" and therefore serves to help distribute strain in a more normalized fashion. Transection of the CAL substantially alters strain patterns, resulting in increased strain at the scapular spine following RSA., Clinical Relevance: CAL preservation is a modifiable risk factor that may reduce the risk of bone microdamage and thus the occurrence of fatigue/stress fractures in the scapular spine following RSA.

Hypothesis: We aimed to describe a modified surgical technique to treat isolated sternocostal head tears using cortical button fixation while preserving the intact clavicular head tendon, to outline a new classification of pectoralis major injuries, and to present the clinical outcomes and return-to-sport data of a cohort of 21 athletes who underwent surgical repair., Methods: We reviewed prospectively collected data of patients who underwent surgical repair with the described technique for isolated sternocostal head tears from 2008 to 2014. Two-year postoperative clinical outcomes including the Single Assessment Numeric Evaluation score, isokinetic strength, patient satisfaction, and return to sport, as well as preinjury and postoperative bench-press weight, were collected, and descriptive statistics were used for analysis., Results: Twenty-one patients who underwent repair of isolated sternocostal head tears were included. The majority of the isolated tears of the sternocostal head of the pectoralis major (57%) occurred during the bench press. Of the ruptures, 81% were Tietjen type IIIC and 19% were type IIID. Postoperative Single Assessment Numeric Evaluation scores averaged 90.1 (standard deviation, 8.4), and patient satisfaction was 9.5 of 10 (standard deviation, 0.9). All athletes returned to sport approximately 5.5 months postoperatively. The isokinetic strength deficit averaged 8% compared with the contralateral arm, whereas the average preinjury bench-press weight of 134 kg (range 88-227 kg) was restored to 117 kg (range 61-250 kg) postoperatively., Conclusion: We propose a new classification of pectoralis major injury. In addition, we present a biomechanically sound repair technique for isolated tears of the sternocostal head of the pectoralis with favorable outcomes. The technique takes the specific anatomy of the sternocostal and clavicular heads into account for the approach., (Copyright © 2019 Journal of Shoulder and Elbow Surgery Board of Trustees.

Background: Shoulder instability in young athletes is a complex problem with higher recurrence, higher reoperation, and lower return to sport (RTS) rates after arthroscopic shoulder stabilization compared with adults., Methods: This is a prospective case series of young athletes with anterior shoulder instability after arthroscopic stabilization surgery. Primary outcomes were RTS and revision surgery, minimum follow-up was 24 months. Exclusion criteria were more than 3 preoperative episodes of instability, significant bone loss, or primary posterior instability. Demographic data, recurrent instability, revision surgery, sports pre- and postsurgery, patient satisfaction, level of RTS, time to RTS, and Single Assessment Numeric Evaluation (SANE) scores were analyzed., Results: Sixty-seven athletes met inclusion criteria, 19 females and 48 males, with a mean age of 17.5 years (range, 13-21 years). Fifty-nine (88%) athletes returned to sport at an average of 7.1 months (standard deviation, ±1.8); 50 (75%) returned to the same level or higher. Football and lacrosse were the most common sports. Four of 67 athletes (6%), all male, underwent revision stabilization at 11-36 months for recurrent instability. The overall mean SANE score was 88., Conclusion: This study demonstrates that when the high-risk athlete, 21 years old or younger, is appropriately selected for arthroscopic shoulder stabilization by excluding those with 3 or more preoperative shoulder instability episodes and those with off-track and engaging instability patterns, excellent outcomes can be achieved with low revision surgery rates, high RTS rates, and high patient satisfaction., (Copyright © 2019 Journal of Shoulder and Elbow Surgery Board of Trustees.

Recent literature has identified a population of active adolescents aged 13 to 15 years who are at high risk for anterior cruciate ligament graft rupture. Addressing the anterolateral complex during primary anterior cruciate ligament reconstruction has recently re-emerged in the literature, with various techniques available. This paper aims to describe a lateral extra-articular tenodesis procedure using the iliotibial band with a modified Lemaire technique. This procedure is recommended for active adolescents at a high risk of graft re-tear as an enhancement to primary anterior cruciate ligament reconstruction with soft-tissue graft., (© 2019 by the Arthroscopy Association of North America.

Background: The purpose of this study was to evaluate the psychometric properties of the Patient-Reported Outcomes Measurement Information System (PROMIS) physical function computer adaptive test (PF-CAT) relative to the American Shoulder and Elbow Surgeons (ASES) score in patients with glenohumeral osteoarthritis undergoing primary anatomic total shoulder arthroplasty (TSA)., Methods: A retrospective study of an institutional TSA registry was performed. Preoperative PROMIS PF-CAT and ASES scores were collected. Floor and ceiling effects were determined, and convergent validity was established through Pearson correlations. Rasch partial credit modeling was used for psychometric analysis of the validity of PF-CAT and ASES question items. Person-item maps were generated to characterize the distribution of question responses along the latent dimension of shoulder disability., Results: Responses from 179 patients (184 shoulders) were included. PF-CAT had a moderate correlation to ASES (r = 0.487; P < .001), with no floor or ceiling effects; ASES had a 1.1% floor effect and no ceiling effect. With iterative Rasch model item-reduction analysis eliminating poorly fitting question items, all possible PF-CAT items were eliminated after 6 iterations. With ASES, just 1 function question item was dropped. Person-item maps showed ASES to be superior to PROMIS PF-CAT psychometrically, with sequential and improved coverage of the latent dimension of shoulder disability., Conclusion: Despite moderate correlation with ASES, PROMIS PF-CAT demonstrated inferior validity and psychometric properties in patients undergoing TSA. PF-CAT should not replace the ASES in this population of patients., (Copyright © 2019 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc. All rights reserved.)

Background: This study assessed the current political standings and active political engagement of American Shoulder and Elbow Surgeons (ASES) members along with the political process as it relates to health care policy., Methods: This survey study involved 552 ASES members. The survey was open for 2 weeks. Responses were received from 254 of the 552 members (46%), and their answers were analyzed., Results: Six (2%) of the responding members were solo practitioners, 100 (39%) belonged to a private practice, 106 (42%) were providers at academic institutions or residency training programs, 25 (10%) were employed by a hospital, and 17 (7%) categorized themselves as other. Email was the preferred method of communication. Of all responding members, 110 (43%) stated they had contributed to the American Academy of Orthopaedic Surgery Political Advocacy Committee in the last 12 months. Four (10%) of the responding members have a relationship with an elected official, and 220 (87%) would be willing to become a key contact and reach out to a legislator., Conclusion: Moving forward, this survey can be used to better shape the political advocacy efforts of the ASES and potentially other subspecialty societies. The response that "a high percentage of members would like to be more involved" suggests the need for a program to help further educate and facilitate the membership on political advocacy., (Copyright © 2018 Journal of Shoulder and Elbow Surgery Board of Trustees.

Background: With sports specialization and level of competition on the rise, anterior cruciate ligament reconstruction (ACLR) in athletes under the age of 20 has increased significantly in recent years. Reports have demonstrated that the revision ACLR rate is higher and return to sport (RTS) rate is lower in this population., Purpose: To evaluate the 2-year clinical outcomes of 3 cohorts of primary ACLR in pediatric and adolescent athletes under the age of 20 based on skeletal age with a focus on RTS and the incidence of second surgery., Study Design: Case series; Level of evidence, 4., Methods: This is a prospective evaluation of 324 athletes younger than 20 years of age who underwent ACLR with minimum 2-year follow-up. The surgical technique was selected predicated on skeletal age, which includes the all-epiphyseal technique with hamstring autograft in the youngest cohort in elementary and middle school (group 1), the partial transphyseal and complete transphyseal with hamstring autograft performed for athletes in the middle cohort (group 2), and bone-tendon-bone autograft in the skeletally mature high school athletes (group 3)., Results: The mean chronological age of the entire cohort was 15 years (range, 8-19 years) with 55% males. The 3 cohorts included 49 patients (15%) in group 1 (mean age, 12 years), 66 (20%) in group 2 (mean age, 14.3 years), and 209 (65%) in group 3 (mean age, 16.2 years). Group 2 athletes had a significantly higher revision ACLR rate (20%) compared with group 1 (6%; P = .039) and group 3 (6%; P = .001). Similarly, group 2 athletes had significantly lower RTS rates (85%) compared with group 1 (100%) and group 3 (94%)., Conclusion: The rate of revision ACLR was significantly higher and the RTS rates significantly lower in group 2 compared with groups 1 and 3. This age-related risk profile may be used to counsel athletes and parents preoperatively regarding the expectations of surgery with respect to revision ACLR and RTS rates.

Introduction: The purpose of this study was to determine whether surgical arthroscopic decompression or ultrasound-guided aspiration of a paralabral cyst would result in suprascapular nerve recovery from axonal regeneration based on electrodiagnostic testing., Methods: Nine patients with preoperative electromyography (EMG) evidence of suprascapular neuropathy due to paralabral cysts at the suprascapular or spinoglenoid notch were prospectively studied. Eight patients underwent arthroscopic surgical decompression, and 1 patient underwent ultrasound-guided aspiration. Postoperative EMG was performed in all patients to evaluate nerve regeneration., Results: Three (33%) patients had cysts at the suprascapular notch, whereas 6 (67%) patients had cysts at the spinoglenoid notch. All patients showed complete electrophysiological recovery after decompression., Discussion: Decompression of paralabral cysts at the suprascapular or spinoglenoid notch resulted in postoperative EMG evidence of nerve recovery. Long-term studies with a greater number of patients are required to elucidate time to recovery. Muscle Nerve 59:247-249, 2019., (© 2018 Wiley Periodicals, Inc.)

Injury to the anterior cruciate ligament (ACL) is becoming increasingly common in the skeletally immature population. Historically, there was a reluctance to operate on skeletally immature patients due to potential damage to the physis and subsequent growth disturbances; however, more recently, ACL reconstruction techniques specifically developed for this young population have shown good outcomes and low complication rates. In this article, we briefly discuss the modifiable and non-modifiable risk factors for ACL injury in children, options for conservative management for ACL rupture, and outcomes for delayed operative management. The main focus of the manuscript is to describe three operative technique options designed for ACL reconstruction in skeletally immature patients and to review the literature on outcomes and complications of these techniques. Two of these techniques, namely the Modified MacIntosh and the all-epiphyseal techniques, are often referred to as physeal-sparing, while the third, i.e. the transphyseal technique, is not. While different in approach and technique, these procedures have been shown to produce good outcomes and minimal complications in the skeletally immature population. Despite these positive reports, it is also essential to be aware of potential complications and the potential risk of recurrence.

Background: Reinjury rates after anterior cruciate ligament reconstruction (ACLR) are highest among young athletes, who consequently suffer from low rates of return to play. Historically, quantitative measures have been used to determine readiness to return to sport; however, they do not assess modifiable risk factors related to the quality of movement., Purpose: To determine the effectiveness of a criteria-based rehabilitation progression and return-to-sport criteria on efficient return to activity and prevention of second injury in young athletes post-ACLR., Study Design: Case series; Level of evidence, 4., Methods: Between December 2010 and 2013, 42 skeletally immature athletes (mean chronologic age, 12 years; range, 10-15 years) who underwent ACLR using ipsilateral hamstring tendon autograft were prospectively evaluated. All athletes progressed through a criteria-based rehabilitation progression; were assessed at specific time frames for strength, biomechanical, and neuromuscular risk factors predictive of injury; and were provided targeted interventions. The final return to sport phase consisted of quantitative testing as well as a quality of movement assessment of several functional movements with progressive difficulty and sports-specific loading. Clearance for unrestricted activity was determined by achieving satisfactory results on both qualitative and quantitative assessments with consideration for the demands of each sport., Results: The mean time for return to unrestricted competitive activity was 12 months. All but 3 (7%) athletes returned to their primary sport. Thirty-five athletes (83%) returned to unrestricted activity. Of the 6 (14%) who sustained a second injury, 3 (50%) were injured in sports they were not cleared for. All ACL reinjuries occurred in a cutting sport. Half of reinjuries occurred within 1 year of surgery, while the remaining occurred between 1 and 2 years. Eighty-three percent of reinjuries involved highly competitive cutting athletes., Conclusion: In our cohort, the combination of qualitative and quantitative data served as a good indicator for reducing risk and determining readiness to return to sport., Competing Interests: The authors declared that they have no conflicts of interest in the authorship and publication of this contribution.

Background: There are limited data on the outcomes of surgically repaired pectoralis major tendon (PMT) tears. The purpose of this study was to report the functional outcomes, return to sport, and second surgery rates in a consecutive series of PMT tears., Methods: Forty patients with acutely repaired PMT tears were retrospectively identified. Follow-up was conducted with functional outcome scores and adduction strength testing at final follow-up. Return to sport and incidence of subsequent surgery were also recorded., Results: The average age of the patients was 34.4 years (range, 23-59 years). Average follow-up was 2.5 years (range, 2-7.0 years). Twenty-three injuries (58%) occurred in the nondominant extremity. Bench press (n = 26) and contact sport participation (n = 14) were the most common mechanisms. Postoperative Single Assessment Numeric Evaluation scores averaged 93.6 (range, 62-100), with patient satisfaction of 9.6 of 10 (range, 6-10). All athletes returned to preinjury level of function approximately 5.5 months postoperatively (range, 4.5-6.5 months); 23.1% and 2.6% described mild or moderate difficulties with sport participation. Isokinetic strength evaluation revealed an average decrease of 9.9% (range, -18% to 41%). Application of the Bak criteria revealed 37% excellent, 26% good, and 37% fair outcomes, with most in the fair group reporting cosmetic concerns. Removing cosmesis, 46% scored excellent, 37% good, and only 17% fair. Three athletes required a second surgical procedure (7.5%)., Conclusions: Surgical repair of PMT tears resulted in high patient satisfaction, with excellent restoration of function and adduction strength, early return to sport, and few reoperations, albeit with the potential for mild cosmetic concerns., (Copyright © 2017 Journal of Shoulder and Elbow Surgery Board of Trustees.

Background: Anterior cruciate ligament (ACL) injuries in skeletally immature athletes are increasing., Purpose: To evaluate the 2-year clinical outcomes of all-inside, all-epiphyseal ACL reconstruction in skeletally immature athletes with 3 to 6 years of remaining growth, with a focus on return to sport and the incidence of second surgery., Study Design: Case series; Level of evidence, 4., Methods: Twenty-three skeletally immature athletes were prospectively evaluated after all-epiphyseal ACL reconstruction utilizing a hamstring autograft. The athletes' age, sex, sport, mechanism of injury, radiographs, and magnetic resonance imaging (MRI) findings were noted. The evaluation included a physical examination, KT-1000 arthrometer measurements, isokinetic testing, and validated outcome scores. Standing radiographs and spoiled gradient recalled echo MRI scans were obtained at 6, 12, and 24 months postoperatively. A quality of movement assessment and return-to-sport performance analysis were also performed., Results: Of the 23 athletes, 6 were female (mean age, 11.3 years), and 17 were male (mean age, 12.6 years). At a minimum follow-up of 2 years (range, 24-45 months), the mean International Knee Documentation Committee score was 94.6 ± 4.9, the mean Lysholm score was 97.9 ± 4.0, the mean Marx activity rating scale score was 13.4 ± 3.6, and the mean Hospital for Special Surgery Pediatric Functional Activity Brief Scale score was 23.9 ± 7.0. Lachman and pivot-shift test results were negative in all patients. The mean side-to-side difference on the KT-1000 arthrometer was 0.9 ± 0.5 mm and less tight on the operated side. No significant growth disturbances were noted; however, 6 athletes had a leg-length discrepancy of more than 5 mm (range, 6-18 mm). Two patients had overgrowth in the femur of more than 15 mm (16 mm and 18 mm). Two athletes (8.7%) required second surgery. The mean time to return to unrestricted activity was 13.5 months (range, 8-22 months)., Conclusion: The all-inside, all-epiphyseal ACL reconstruction technique using a hamstring autograft demonstrates excellent subjective and objective clinical outcomes in skeletally immature athletes without physeal arrest.

Background: Rupture of the short head component of a bifurcated distal biceps tendon is a rare injury that may be difficult to diagnose and to treat., Methods: Three cases of patients with selective disruption of the short head of the biceps distal tendon from a single institution are reported. The presenting history, physical examination, imaging studies, operative findings, and treatment strategies are described., Results: In each case, the mechanism of injury was forceful flexion of the involved elbow against an eccentric load. Notable physical examination findings included a palpable tendon in the antecubital fossa, a "reverse Popeye" deformity, and pain and weakness with resisted forearm supination and elbow flexion. Careful review of the magnetic resonance imaging studies demonstrated the classic findings for this unique injury. All 3 patients successfully returned to their baseline level of activity after anatomic repair of the short head component with or without independent repair of the long head component (depending on the degree of partial tearing seen intraoperatively)., Discussion/conclusions: Rupture of the short head component of a bifurcated distal biceps tendon is a rare injury that can be easily misdiagnosed and mistreated. A meticulous physical examination and evaluation of imaging is required to differentiate this injury from a partial or complete tear of a common distal biceps tendon. Clinicians should maintain a high index of suspicion for this unusual injury pattern. When it is diagnosed appropriately, selective disruption of the short head of the biceps distal tendon may be effectively treated with anatomic repair., (Copyright © 2017 Journal of Shoulder and Elbow Surgery Board of Trustees.

Purpose of Review: As anterior cruciate ligament (ACL) injury is becoming increasingly prevalent in the population of active children and young adolescents, it is crucial to be aware of both the modifiable and nonmodifiable factors that place this population at increased ACL injury risk. Historically, there has not been a definitive consensus on all of these risk factors-particularly the nonmodifiable ones., Recent Findings: The present review has accumulated the most recent evidence for the nonmodifiable risk factors in ACL injury focusing particularly on female gender, generalized joint laxity, knee recurvatum, increased lateral tibial slope, decreased intercondylar notch width, structural lower extremity valgus, limb length discrepancy, family history, and history of contralateral knee ACL injury., Summary: Physicians should be aware of the nonmodifiable risk factors for ACL tears in active children and adolescents and should also encourage avoidance of modifiable risk factors in this population. Young athletes with nonmodifiable risk factors are at a particularly increased risk of recurrent injury following ACL reconstruction (ACLR). We believe that a primary extra-articular augmentation via iliotibial band tenodesis at the same time of ACLR may decrease the rate of reinjury for the high risk athlete with multiple nonmodifiable risk factors.

Purpose of Review: In the young athlete, the shoulder is one of the most frequently injured joints during sports activities. The injuries are either from an acute traumatic event or overuse. Shoulder examination can present some challenges; given the multiple joints involved, the difficulty palpating the underlying structures, and the potential to have both intra- and/or extra-articular problems., Recent Findings: Many of the shoulder examination tests can be positive in multiple problems. They usually have high sensitivity but low specificity and therefore low predictive value. The medical history coupled with a detailed physical exam can usually provide the information necessary to obtain an accurate diagnosis. A proficient shoulder examination and the development of an adequate differential diagnosis are important before considering advanced imaging., Summary: The shoulder complex relies upon the integrity of multiple structures for normal function. A detailed history is of paramount importance when evaluating young athletes with shoulder problems. A systematic physical examination is extremely important to guiding an accurate diagnosis. The patient's age and activity level are very important when considering the differential diagnosis. Findings obtain through history and physical examination should dictate the decision to obtain advanced imaging of the shoulder.

Background: Early sport specialization is not a requirement for success at the highest levels of competition and is believed to be unhealthy physically and mentally for young athletes. It also discourages unstructured free play, which has many benefits., Purpose: To review the available evidence on early sports specialization and identify areas where scientific data are lacking., Study Design: Think tank, roundtable discussion., Results: The primary outcome of this think tank was that there is no evidence that young children will benefit from early sport specialization in the majority of sports. They are subject to overuse injury and burnout from concentrated activity. Early multisport participation will not deter young athletes from long-term competitive athletic success., Conclusion: Youth advocates, parents, clinicians, and coaches need to work together with the sport governing bodies to ensure healthy environments for play and competition that do not create long-term health issues yet support athletic competition at the highest level desired.

Background: Increased posterior tibial slope is associated with increased risk of anterior cruciate ligament (ACL) injury in adults. A similar association has not been rigorously examined in children and adolescents., Purpose: To determine whether alterations in posterior tibial slope are associated with ACL tears in pediatric and adolescent patients and to quantify changes in tibial slope by age., Study Design: Case-control study; Level of evidence, 3., Methods: Magnetic resonance imaging (MRI) studies of the knee were reviewed by 3 raters blinded to each other in a 1:1 sample of cases and age- and sex-matched controls. A total of 76 skeletally immature ACL-injured knees were compared with 76 knees without ACL injury; the mean age of the study population was 14.8 ± 1.3 years. The posterior slope of the articular surface of the medial tibial plateau and lateral tibial plateau was measured by use of a method similar to that used in previous studies in adult populations. The current study technique differed in that the slope was measured on the cartilage surface, not the subchondral bone. Comparisons between knees were made with t tests, and Spearman correlation analysis was used to assess changes in tibial slope with advancing age., Results: Increased slope of the lateral tibial plateau (LTS) was significantly increased in ACL-injured patients compared with controls (5.7° ± 2.4° vs 3.4° ± 1.7°; P < .001). There was no statistically significant difference in the slope of the medial tibial plateau (MTS) in the ACL-injured and control knees (5.4° ± 2.2° vs 5.1° ± 2.3°; P = .42). There was no difference in LTS between male and female patients (4.46° vs 4.58°; P = .75). Receiver operating characteristic (ROC) analysis of the LTS revealed that a posterior tibial slope cutoff of >4° resulted in a sensitivity of 76% and a specificity of 75% for predicting ACL tears in this cohort. Spearman correlation analysis revealed that MTS and LTS decreased, or flattened, by 0.31° (P = .028, correlation coefficient r = -0.18) and 0.37° (P = .009, correlation coefficient r = -0.21) per year, respectively, as adolescents age., Conclusion: The LTS was significantly associated with an increased risk of ACL injury in pediatric and adolescent patients. The MTS was not associated with risk of injury. Posterior slope was found to decrease, or flatten, with age. A cutoff of >4° for the posterior slope of the lateral compartment is 76% sensitive and 75% specific for predicting ACL injury in this cohort. The LTS did not influence the incidence of ACL injury differently between sexes., (© 2015 The Author(s).)

Background: Anterior cruciate ligament (ACL) reconstruction in skeletally immature patients can result in growth disturbance due to iatrogenic physeal injury. Multiple physeal-sparing ACL reconstruction techniques have been described; however, few combine the benefits of anatomic reconstruction using sockets without violation of the femoral or tibial physis., Purpose: To utilize physeal-specific magnetic resonance imaging (MRI) to quantify the zone of physeal injury after all-inside ACL reconstruction in skeletally immature athletes., Study Design: Case series; Level of evidence, 4., Methods: Twenty-three skeletally immature patients (mean chronologic age 12.6 years; range, 10-15 years) were prospectively evaluated after all-inside ACL reconstruction. The mean bone age was 13.2 years. There were 8 females and 15 males. Fifteen patients underwent an all-epiphyseal (AE) ACL reconstruction and 8 patients had a partial transphyseal (PTP) ACL reconstruction, which spared the femoral physis but crossed the tibial physis. At 6 and 12 months postoperatively, MRI using 3-dimensional fat-suppressed spoiled gradient recalled echo sequences and full-length standing radiographs were performed to assess graft survival, growth arrest, physeal violation, angular deformity, and leg length discrepancy., Results: The mean follow-up for this cohort was 18.5 months (range, 12-39 months). Minimal tibial physeal violation was seen in 10 of 15 patients in the AE group and, by definition, all patients in the PTP group. The mean area of tibial physeal disturbance (±SD) was 57.8 ± 52.2 mm(2) (mean 2.1% of total physeal area) in the AE group compared with 145.1 ± 100.6 mm(2) (mean 5.4% of total physeal area) in the PTP group (P = .003). Minimal compromise of the femoral physis (1.5%) was observed in 1 case in the PTP group and no cases in the AE group. No cases of growth arrest, articular surface violation, or avascular necrosis were noted on MRI. No postoperative angular deformities or significant leg length discrepancies were observed., Conclusion: The study data suggest that all-inside ACL reconstruction is a safe technique for skeletally immature athletes at short-term follow-up. Physeal-specific MRI reveals minimal growth plate compromise that is significantly lower than published thresholds for growth arrest., (© 2014 The Author(s).)

In addition to operative intervention for the patient with recurrent shoulder instability, current literature suggests that younger athletic patients unwilling to modify their activities may benefit from an early surgical shoulder stabilization procedure. Although open shoulder stabilization clearly has a role to play in some cases, we believe that further optimization of arthroscopic fixation techniques may allow us to continue to refine the indications for open stabilization. In particular, when an arthroscopic approach is used for capsulolabral repair in relatively high-risk groups, it may be beneficial to use a double-row repair technique. We describe our technique for shoulder stabilization through double-row capsulolabral repair of a soft-tissue Bankart lesion in the high-risk patient with shoulder instability or the patient with a small osseous Bankart lesion.
